The neutron capture therapy device comprises a neutron dose measurement apparatus (21) and a correction system (3) for correcting the neutron dose measurement apparatus (21), wherein the neutron dose measurement apparatus (21) comprises a detector (211) used to receive neutrons and output electrical signals, a signal processing unit (212) used to process the electrical signals output from the detector (211) and convert the electrical signals into pulse signals, and a counter (213) used to count the pulse signals output from the signal processing unit (212) to obtain a count rate.

A method comprises presenting, by a server for display on a screen associated with a radiotherapy machine, a series of consecutive graphical user interfaces (GUIs), wherein a first GUI comprises: a first graphical indicator (GI) corresponding to a first attribute associated with configuration of the radiotherapy machine, and a second GI corresponding to a second attribute associated with the patient; when the server receives an indication that a user interacting with a pendant in communication with the server has inputted a first input corresponding to a first direction towards the first GI, presenting for display a second GUI comprising data associated with the first attribute; and when the server receives an indication that the user has inputted a second input corresponding to a second direction towards the second GI, presenting for display a third GUI comprising data associated with the second attribute.

The present disclosure provides a neutron capture therapy system, including an accelerator for generating a charged particle beam, a neutron generator for generating a neutron beam having neutrons after irradiation by the charged particle beam, and a beam shaping assembly for shaping the neutron beam. The beam shaping assembly includes a moderator and a reflecting assembly surrounding the moderator. The neutron generator generates the neutrons after irradiation by the charged particle beam. The moderator moderates the neutrons generated by the neutron generator to a preset energy spectrum. The reflecting assembly includes a reflecting assembly to deflected neutrons back to the neutron beam and a supporting member to support the reflectors. A lead-antimony alloy is for the reflecting assembly to mitigate a creep effect that occurs when only a lead material is for the reflectors, thereby improving the structural strength of a beam shaping assembly.

Systems and methods for real-time target validation during radiation treatment therapy based on real-time target displacement and radiation dosimetry measurements.

The present invention relates to a method, a device, and a program for calculating a brachytherapy plan, and a brachytherapy apparatus. The method comprises: a step in which a computer obtains the number of radiation irradiation spots on the basis of radiation irradiation information (a radiation irradiation spot number obtaining step (S200)); a step in which the computer obtains target area information from a body model of a patient generated on the basis of medical image data of the patient (a target area information obtaining step (S400)); and a therapy plan calculating step (S600) in which the computer calculates, on the basis of the radiation irradiation information and the target area information, the radiation irradiation spots to which radiation is irradiated and the time length of irradiation to each radiation irradiation spot.

A radiotherapy device, a method and a computer readable medium are disclosed. The radiotherapy device includes a radiation source and a controller. The radiation source is configured to apply radiation to a subject. The controller is configured to determine an overlap between a defined volume of the subject and an isodose surface and to instruct the radiation source to halt application of the radiation based on the determination.

The trajectory of a beam of charged particles within a patient may be changed by the application of a magnetic field. In that way, the position of the beam's Bragg peak may be controlled for a beam having a specific direction and energy.

A radiotherapy treatment plan for grid therapy in which a patient is radiated from a source of radiation with a set of spatially fractionated beams of charged particles such as protons, including varying the direction of each beam in the set of beams. Generating the plan comprises the steps of determining a first path through the patient to a first Bragg peak position and determining a second path through the patient, at least a part of the second path being directed at an angle from the first path to a first deflected Bragg peak position. The beam directions may be varied by means of magnetic fields or by varying the relative angle between the gantry and the patient.
